Why muscles have to work in pairs?
Skeletal muscles only pull in one direction. For this reason they always come in pairs. When one muscle in a pair contracts, to bend a joint for example, its counterpart then contracts and pulls in the opposite direction to straighten the joint out again.
Tissue that can contract and shorten?
The Muscle tissue is the one to contract and shorten when it moves or stretches it pulls on the bone to create movement and it shortens and in some cases it contracts
How does the elbow work like a lever?

Where would you find your corrugator?

What does muscles work in pairs mean?
Skeletal muscles are arranged as opposing pairs because, although they can shorten themselves by contracting, they have to be stretched back to their former length by other muscles. An example of opposing muscles is in the arm, where the biceps and triceps have opposite actions. As one muscle shortens, the other is stretched. The biceps contracts to bend the arm at the elbow while the triceps stretches. To straighten the elbow joint, the triceps contracts, while the biceps stretches.
How can tendons pull bone?
on one end of a tendon comes from the muscles while the other hand is attached to a bone,then it pulls
How does the muscular system interact with skeletal system to create movement?
Muscles are attached to tendons which connect to bones. When a skeletal muscle contracts, it pulls on the tendon which in turn pulls on the bone, causing it to move.
When you jumped which or who exerted a force on you?
When you jump up your muscles in your legs exert a force on your bones to push you off the ground. The muscles are attached to the bones to have leverage. So when your muscle pulls, the leg bone moves on a hinge or joint and the bones push off the ground.
